| الملخص: | <p dir="ltr">A new fouling-resistant mixed-matrix nanofiltration membrane based on a covalently cross-linked Ti<sub>3</sub>C<sub>2</sub>T<sub>X</sub> (MXene)/cellulose acetate (MXene@CA) composite was fabricated by phase inversion followed by formaldehyde cross-linking. The physicochemical properties of the prepared MXene@CA composite membranes were studied by field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and water contact angle techniques. The performance of the prepared membranes was evaluated with respect to the water flux, bacterial growth inhibition, and rejection properties. The 10%MXene@CA (10:90 wt % of MXene:CA) composite membrane shows high pure water flux of ~256.85 L m<sup>−2</sup> h<sup>−1</sup> bar<sup>−1</sup>, 123.28% water uptake, and 69.7% porosity. The 10%MXene@CA membrane, exhibited more than 92% and 98% rejection of rhodamine B (RhB) and methyl green (MG), respectively. Furthermore, 10%MXene@CA membrane exhibited more than 98% and 96% growth inhibition for <i>E. coli</i> and <i>B. subtilis</i>, respectively. Also, the optimal membrane showed a significantly improved hydrophilicity (water contact angle = 60.8°), which has favored good antifouling properties. The reported nanofiltration membrane, especially 10%MXene@CA, can be suggested for water purification and biomedical applications.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Membrane Science<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.memsci.2020.118139" target="_blank">https://dx.doi.org/10.1016/j.memsci.2020.118139</a></p> |
